When teachers at a Cheshire primary school were unable to use their recently installed windows, K2 Aluminium Systems and the Glazerite UK Group replaced them, making them fit for use.

Though Veka profiles had been specified for the original install, the contractor had used another system. This had resulted in bowed sashes and inoperative windows, as well as window screen walling that shook when pressed.

Wirral-based K2 has worked extensively on new build and replacement projects, ranging from retail units and offices to schools and hospitals.

Liam Bird, commercial manager for K2, said: “Once we’d carried out our onsite survey, it was obvious the windows used in the install were so badly bowed they wouldn’t close, and the window system had no reinforcement in them at all. We made the correct calculations around wind loads, checked the dimensions, and, in line with Veka and Glazerite’s technical expertise, we made the changes necessary to ensure the new install worked how it should and would perform for years to come.”

K2 installed 47 M70 frames in smooth grey, alongside matching commercial-grade aluminium doors.

Glazerite’s sales manager Peter Smith said: “The windows we fabricated for K2 were fully steel reinforced. The window screens were also coupled together with suitable frame connectors with the correct ‘EI value’, in order to withstand the calculated forces. Veka’s technical expertise is second to none and K2’s installations are always exceptional. As a fabricator we ensured that the school got the correct products, which were well made and installed professionally and efficiently.”
